The show’s hosts asked Calhoun, a professor in the Howe School of Technology Management, about the role of algorithms in high-speed trading.

Algorithms, Calhoun explained, perform the mechanical function of what people did for so long, in terms of trade execution. The difference, of course, is an algorithm can execute trades in the blink of an eye. This sort of high-speed activity has changed trading strategies and created concern from regulators and others, who are hesitant about the impact such technology can have.

“It’s technology and the speed that creates all the risks that we are now coping with,” Calhoun told the hosts.
